HECTOR M. JOHNSTON, OF EAU CLAIRE, WISCONSIN.

PUMP.

SPECIFICATION forming part of Letters Patent No. 276,048, dated April 17, 1883.

Application filed January 13, 1883.

To all whom it may concern Be it known that I, HECTOR M. JOHNSTON, a citizen of the United States of America, residing at Eau Claire, in the county of Eau Claire and State of Wisconsin, haveinvented certain new and useful Improvements in Pumps; and 1 do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention relates to certain new and useful improvements in double-acting force and lift pumps; and it consists more especially in providing the same with stationary plungers and in operating the cylinders and water-conveying pipes by means of rods attached to the cylinders, and in the construction and combination of the parts, as will be hereinafter set forth, and pointed out in the claims.

In the annexed drawings, which illustrate my invention, Figure 1 is a front view partly in section. Fig. 2 is a side view, which is also partly in section, and Fig. 3 is a -modification of my invention.

A represents a platform, which is located in the well at a suitable distance above the water-line, to which platform is attached suitable standards, B, having cross-bars O, to which cross-bars are secured the stationary plungers/D D. These plungers are securely attached to the cross-bars, and project down wardly under the same. The platform A is also provided with suitable perforations, a, through which pass the pipes which extend downwardly into the water. These pipes E are provided at a suitable point above the platform Awith connecting-elbows F, to which are attached the discharge-pipes G. At the point to which the pipes G and E are coupled to the elbow F, I provide suitable valves, 0 and g, and on the upper part of these elbows are formed the cylinders H H, which cylinders are provided at their ends with packings It, so as to make a tight joint with the plungers D. These cylinders H are provided with suitable (No model.)

brackets, I, to which the operating-rods are attached, as shown. Located above the surface of the well is a suitable platform, A, which is provided with guideways a, through which pass the ends of the exit-pipes G, the ends of which are curved, so as to bring the discharge openings near each other. This platform is also provided with'perforations, through which pass the operating-rods K, which are attached to the bracket I upon the cylinders H at one end, and on the other end to thepump-handle, which is pivoted to a suitable standard located upon the platform A, as shown.

1f desirable, as shown in Fig.3 of the annexed drawings, the discharge-pipes G may be made in sections, so as to slip within each other, and the discharge-openings may be united by a suitable goose-neck.

It will be seen by the construction hereinbefore described that the valves and cylinders are all located near each other, and the operating parts are formed substantially of one piece, which consists of the valve-seats, operating-cylinder, and connecting-pipes F, as shown.

The operation of this invention, as shown in Figs. 1 and 2, is as follows: v When the handle is'operated one of the cylinders and the water-conveying pipes are depressed while the other is raised, thus creating a suction which draws the waterinto the cylinder above the valve 0, and when the handles are moved in an opposite direction the cylinder is raised upon the plunger, and the water which was drawn within the same by suction is forced out through the valve ginto the dischargepipe G. The handle being pivoted, it will be seen that the whole weight of the operating parts is balanced upon said pivoted handle, with the exception of the plungers. which are secured to the lower platform, and by this means the operating parts all balance each other, and to operate the pump it is only necessary to exert sufficient power to lift the water displaced by the plungers the height of one stroke.

The modifications shown in Fig. 3 operate substantially the same as the arrangement shown in Figs. 1 and "2, though in this case the discharge-pipes Gr slide within the upper discharge-pipe, which is secured stationary to the platform A.

It will also be seen by my invention that the platforms A and A serve as guides for the suction-pipes Gr.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a double-acting force-pump, the combination of the pipes E, provided with connecting-pipes F, having cylinders H, bracket I, and valves 6 and g, and discharge-pipes G, with a standard, B, having attached thereto plungers D and operating means, substantially as shown and described.

2. In a double-acting force and lift pump, the stationary plungers D, attached to the cross-bar O, in combination with the verticallyreciprocating cylinders H, having packingrings h, valves 0 g, and entrance and exit pipes E G, and operating means, substantially as shown.

In testimony whereof I aifix my signature in presence of two witnesses.

HECTOR M. JOHNSTON.
